Does that entail more than microphones? Do you repair equipment? Engineer or build equipment? Microphones, instrument packs, wireless intercoms, wireless in-ear monitors, etc. I do component level troubleshooting and repair. I am not an engineer. I am a high-school "dropout". That being said, I design and build RF amplifier systems, spec fixed filters and have Anatech build them, and tune "agile" cavity bandpass filters. I sweep cables. I coordinate frequencies for "live" TV shows. That sounds like a great job. Good for you. You probably use some kind of TDR to test the cables. Is most of it 75 ohm? I've never worked with "agile cavity bandpass filters". Sounds interesting. I wish we had a TDR. When we get a thousand foot roll of cable we actually unspool the whole mess to see that it's all there. Oddly enough, we do have optical TDRs for fiber, but none for copper. I personally own one, but I don't mingle my tools with the company's. I use my trusty R&S FSH-313. We use these extensively. As soon as we retune them we void the warranty, but have only lost one so far. We use the 4 cavity model. http://www.microwavefilter.com/pdffiles/pg20.pdf I am currently watching Stevie Wonder and the Jonas Brothers, doing "Superstition". |
